ooN, residing atBoston, in the county of Suffolk and .State of Massachusetts, citizens of the vUnited Statesof America, .have invented certain ,new and useful Improvements in X:o Soon-Cleaners for Boilers, of which the following is a specification, reference being had therein to the accompanying drawing. This inventionrelates to certain new and useful improvements in soot cleaners for boilers, and is particularly adapted for use in connection with cleaning the lues vof hori zontal boilers. l

The invention has for its object the provision of a soot cleaner particularly adapted zo for use' in the combustion chamber end of A boilers, for delivery of a soot cleaning agent .iin lthe nature of a gaseous fluid, such as steam, to the. iire, tubes of the boilerin line VNwith the draftof said iire tubes, the cleaner being so mounted as to be rotated. to cover the entire flue area of the boiler, and so arranged that when not in use for cleaning the ilues that it may be withdrawn within the boiler setting so as to be effectually irotect- 3o ed -fromthe action of the heat wit in the combustion chamber. v ith these ends in view the'invention consists in the combination, construction, and i 4arran ement of arts, which will be hereinllbed and claimed. i Reference will be had in the description to ,j the accompanying drawings, forming a'part of this s ecication, and in which drawings similar c aracter's of reference indicate corre- 40 sponding parts throughout` the different views. i

Specification of Letters Patent. Application filed April 9,1907t Serial No. 367,205.

We are aware that heretofore and before our invention, soot cleaners for the'ire tubes of horizontal boilers have been devised for roa boiler, and rotatableso as to cover the entire area of the tubes lat the ends of the boiler. Suclrdevices, however, so faras- We are aware haveV been found commercially livering nozzle' has been so arranged asto be subjected at all times to the intense heat within the combustion chamber, resulting in early injury to the device, and very short ticability of the apparatus. aims to over-come this disadvantage, and we have shown in the accompanying drawings a practical embodiment' of a device embodyin detail. f

boiler and 3, the combustion chamber between the inner face of the boiler settingand the end of the boiler. Y provided on its inner face with a longitudinal recess 4, which is of a length su'llicient to receive' thesteam delivering nozzle of thesoot cleaner to be hereinafter described. Where setting l, and generally insert along the top of the recess a supporting plate 5, for the proximatel "oppositeor in close proximity to the upper ues of the boiler, the steam delivering nozzle' beingr ofl sullicient length f to cover the entire flue area of the boiler end; The soot cleaner embodies in its construction a ipe 6, preferably, though not essentially. a rass' pipe. We prefer to make this pipe of brass, since other parts of the luecleaner an ordinary iron pipe. This pipe -is pro- Per pipe` leading to a suitable steam supply (notlshown). Connected with `the' lower vpassage ofthe T, 7 isaiilrain pipe 9 provided lwith `a suitable shut'off valve 10, a suitable Patented June 25, 19.07,.

As .soon as the dry steam appears through the dripcock 10, the latter is closed and the valve 11 opened, whereupon the dry steam will pass into the cleaner structure through the ipe 6.

The pipe 6 extends into the boiler setting a sulcient length to firmly support the same, being in the present instance shown .as extending nearly to the rear wall of the recess 4.

In connection with the steam delivery pipe 6 we employ an ex ansible joint, which comprises ra sleeve or arrel 12, mounted in thev oiler setting, and provided at its inner end with a collar 14 to abut against the inner slot of the recess 4 and at its outer end with a collar 15 to abut against the outer face of the boiler setting l, thus holding the .sleeve or barrel in fixed position.

Onthe pipe 6, and slidable thereon, is a pipe 16, which extends beyond the outer end ot thev sleeve or barrel 12 and carries on this outer end an operating handle 17 a suitable packing nut or gland 18, being also arranged at the outer end of said pipe 16 to slide on the pipe 6. This construction provides two concentricallyarranged stationary pipes (the `pipe 6 and sleeve12)spaced apart to provide an.

annular space or'passage-way therebetween, Athrough which space the pipe section 16 extends, the pi e 16 being freely movable relatively to sai( stationary pipes without being aected by the steam pressure and without decreasing the size of the steam o ening leadin therefrom. Furthermore, t ere is provi .ed an extended bearing both insidek 4and outside of the pipe 16, insuring the absence of binding, and retaining the pipe section in truel horizontal position irrespective of the weight of the steam delivery structure lo`- -cated at one end of the ipe. `This pipe 16 extends inwardly througi the recess4, and has connected to its inner end an elbow 19 to which is connected a steam delivery ipe or nozzle 20, provided with a plurality o jets or nipples 21.

' n Fig. 1 of the drawings, the device is .shown in position to be rotated, and deliver steam to the fire tubes ofthe boiler. Assuming'the valve 11 to be open, the operator, by manipulating the handle 17 turns the pipe 16' to swing or rotate the nozzle 2() so as toI deliver the steam or other gaseous liquid to all of the fire tubes of the boiler. After the fire tubes have been cleaned, the operator turns the handle so as to bring the nozzle 2() in alinement with the recess 4 in the boiler setting, and then by pulling outward on the handle 17, withdraws the nozzle 2() within the recess 4, away from the heat zone of the combustion chamber where it is'eiectually protected from the heat of said combustion chamber at all times when not in use. To again use the device, it is only necessary to force the handle 17 toward the boiler setting, thus moving pipe 16 inwardly, carrying the steam deliveringr nozzle 2O therewith, so as to project it into the combustion chamber, in

which position it may be again rotated to the limits permitted by the crown of the boiler.

We desire to call attention to the fact that in this device noneof the parts are subjected to the action of the heat within the combustion chamber except when the device is being used, the nozzle at all other times being housed within the boiler setting, out of the zone of the heat of the combustion chamber and ei'iectually protected therefrom.

While we have herein shown and described in detail a practical embodiment of the invention, as the saine has been practiced by ug', yet we do not wish to coniine ourselves to the specified cnstruction shown and d e- Sllbed, as in the practice ofthe invention, Various changes may be madein the details of'construction without departingr from the s irit of the invention or scope thereof, as

escribed in the appended claims.
